K03 hybrid

[MarkB]

I've just found this old thread http://www.rs246.com/index.php?name=PNp ... ic&p=68073

Seems to K03/04 hybrid has been around some time. This time by Turbo Dynamics.

Also now found this http://www.aet-turbos.co.uk/pdf/sb18.pdf

I'm pretty sure those are std K03s and K04s. Speak to Craig@AET about hybrids.

I think that Craig might be the same Craig who used to be at Turbo Dynamics. Not sure though.

Hey MarkB,
Have you decided which route you are going to take?? KO3/KO4 or straight KO4's??


I have been following your threads here and on Buehn,
I think that I have been doing the same turbo research as long as you have.

I have 116k Kms on the clock, ABT chip installed at 28k Km's
I know that I need to change them in the future, hopefully another 6 months down the track.
They sound like a screaming siren at full boost currently
I might take a video and post it up later this week


Cheers
Steve

I've given up on the hybrid route. I don't fancy buying from the US and there's little or no info in the UK.

If I change my turbo's I'll be putting in plain jane K04's. I've decided to keep the car so see it as an investment.

[HK-Steve]

Good to hear that you have made up your mind,
From a reliability point of view, I think that KO4's are the best option.

Are you going to replace the KO3's before they fail, or when they fail??



Cheers
Steve

[MarkB]

Don't know about when I'll replace them yet. Hope for next year or sooner if they fail

Sounds like the one I saw. Just finished searching for it:

As far as a basic write-up on the swap:
-remove headlights, bumper.
-disconnect radiator hoses, power steering lines (use hose block off pliers the steering fluid is like $25 a liter), disconnect A/C lines from condenser.
-there are two torx bolts up top on the front clip, and four on each side on the frame rails. remove these and the entire front clip will come loose. you also may need to remove headlight washer lines (I don't have them as I have a Reiger bumper).
-take the bolts out of the front axles and allow to hang loose, then tie back toward the rear of the car for clearance.
-Once the front end is off remove the intercoolers and intercooler piping the main inlet tubes are held on with o-rings and are very tight, don't be afraid to use a pry bar to pop off.
-You now have access to the turbos, remove the oil and coolant lines (I had a lift so this was much easier)
-unbolt the turbos from the manifolds and the manifolds from the heads.
-unbolt the heat shields and then the downpipes, unplug the front 02 sensors
-remove the manifolds through the front of the car (I had to pry on the driver side of the engine for clearance to get the manifold on that side)
- the pass side turbo will come out the front of the car from underneath.
-the driver side turbo will cone out from the bottom almost straight down (you can pull this without removing the manifold but it's much easier if you do)
-remove the oil drain and fill lines and clean
-re-install is the opposite of removal.
- also you will have access to do a timing belt, water pump, serp belt, etc. I recommend doing while this far along.

-tools required- Metric ball-end Allen socket set, 8mm and 6mm straight Allen sockets, 10-spline socket driver set (to loosen the axles), metric socket set, pry bar set, Phillips and flat head screwdrivers, metric box end wrench set, etc.

-notes: my car has an aftermarket bumper with custom intercooler supports, I removed the A/C completely with my swap, I reinstalled with aftermarket manifolds which took a lot more work to get into the car than the stock ones coming out. Tools required is to the best of my recollection as I had the help of a tech, a lift, and 8 master-techs tools available to me. I'll post anything else that comes to mind.

must say this thread makes very interesting reading, did anyone remove there turbo's with engine in situ?
i removed mine last week didnt take any photo's im afraid,was as text above but i ended up taking off engine mounting on drivers side to remove turbo through front of engine bay, time taken was 5hrs total

turbo's did turn out to be hybrid k03/k04's had taken a good beating just in time before failure.


im now awaiting my refurbed k04's to be returned to me a then slow process of refitting them

then i will make my way to powerstation for remap

Guys there is a company now that hybrids K03 and K04 turbo called Scroll who do the SP51 conversion.

I have just had a dead K04-15 for my 1.8T converted to there hybrid Outlaw which a standard K04-15 turbo with injectors 3" MAF, injectors, exhaust , FMIC and 5br FPR and a remap was only good for around 245bhp. Well now one of the guys on another forum is running the hybrid K04 on his car with just an exhaust and a remap is getting 243bhp.

Now I know the K04's for the S4 are bigger but I was aware they where doing RS4 k04's and can convert K03's to K04 spec.

Oh and they change the CHAR’s to twin oil feed so better reliability cost me for the conversion $650 and they are based in Poland.
